In China, you have to be extra careful:
1, #Bitcoin "has property attributes", but it is not a currency, just a valuable commodity, so it is illegal for enterprises to pay wages with virtual currency.
2, #BTC mining machine "has property attributes", but mining is illegal.
3, Buying a mining machine with fiat currency is a valid contract, protected by law, and you can defend your rights if you are cheated.
4, Buying a mining machine with #Crypto is an invalid contract, not protected by law, and you can only admit defeat if you are cheated...
5, Giving money to let others help invest in virtual currency, bear the risk yourself, not protected by law.
6, Offline OTC can defend their rights if they are robbed, cheated, or stolen.
You have to understand everything, otherwise you will have no place to reason if you are cheated..
